中文摘要：

用序批式生物膜反应器（SBBR）处理南方地区城市污水，在气量从30L·h^-1提升到100L·h^-1（平均DO范围为2．75～5．20mg·L^-1）的过程中均能有效地实现亚硝酸型同步硝化反硝化．综合反应时间和脱氮效果，气量为60L·h^-1（平均D0为4．25mg·L^-1）时具有最佳脱氮效率，可以作为处理南方地区城市污水SBBR亚硝酸型同步硝化反硝化工艺的控制参数．

英文摘要：

Using the sequencing batch hiofilm reactor （SBBR） to treat municipal sewage of south area,the air flux range from 30 L ·L^-1 to 100 L ·L^-1 （ the concentration of average oxygen range from 2.75 to 5.20 mg ·L^-1） was proved very efficient for SND via nitrite. Considering the reaction time and TN removal rate ,60 L·L^-1 （ the concentration of average oxygen was 4.25 mg ·L^-1） was the best air flux. And the 4.25 mg·L^-1 concentration of average oxygen can be considered as the control parameter of using simultaneous nitrification and denitrification via nitrite technique in SBBR to treat municipal sewage of south area.
